ATENT F 1 cLosEn AUTO BODY VENTILATOR.

Application filed September 10, 1927. Serial No. 218,684.

The object of invention is to provide a ventilating device adapted for installation system whereby the upper air currents may.-

be intercepted and ejected from the auto 15 body, and especially any smoke that may be caused by occupant smoking therein, and which naturally rises to the roof of the auto body, the same being carried to the rear of the car by air currents when the auto is in motion.

is simple in construction, easily and efiicient ly operated and can be manufactured at a very low cost. These several objects are 1 attained in the preferred form by the construction and arrangement of parts more.

fully hereinafter set forth.

Similar parts on all drawings are-marked bysimilar numerals. t V Fig. 1 shows a'front view of my device as assembled and ready for installation within an automobile body. V

Fig. 14 is an outside view of an auto body showing the installation of the device-and the position of the lators. r

I will now described more fully my device, referring to the drawings and the marks thereon. v I ,In general my device comprises anopen tubular section for installation across the rear inside wall of a closed automobile body,

exterior suction ventiand provided with an air deflecting plane. i

The tubular section is extended through the side walls of the auto body and turned to-.

ward "the rear of the body, carrying thereon special air suction ventilators for. causing a. suction within the ventilator tube. F or simplicity in construction, and for. slmplicity in illustration of my device, the

ventilator tube 1 and the deflector shield 2- are formed of a continuous piece of sheet metal, of a length to extendthe width of the auto body in which it'is to be installed. The tube -1 is formed in approximately a cylindrical formation but providing an opening -3 between the sheet edge and the deflector shield 2, also extending the, I

entire. length of the tube -1. The deflector shield -2 is formed by continuing the metal sheet in approximately an S shaped curve of a design corresponding to the usual curved corner 4 ordinarily formed in the present day car construction, as illustrated in Fig. 12. The tube 1 auto body and may be attached thereto by any convenient means for holding same in a fixed position therein. v Through openings in the side walls 6 of the auto body are mounted the suction ventilators 7-, positioned therein to fit and engage'the ends is placed along the rearwall '5f of the 1 of the ventilator tube 1 at both ends,

and openathe'rein. The suction ventilators 7 comprise a hollow tubular elbow section -8 designed to pass through the auto body wall -6 and engage the" ventilator tube l within the auto body, for continuing the passage outside thebodywalls. The curved elbows are positioned atolead toward the rear of car body. A flange collar --9' is formed inv the tubular elbow -8 for fitting the outer body walls and :are fixedly attached thereto 'by .the. screws -10 passing through the flange :ho'les. Fixedly attached :to the flanged collar --9 is ;a flattened tubular casing l1t, placed at .right angles to theiaxisof the ventilator tube -1 and attached =to-the auto body dnza horizontal position, inclosing therein the tubular elbow outlet .at the :rear end thereof. Within the flattened tubular -casing-l1- is mountedra conical suction .ztube -13, fixedly attached to the casing along the .axis

therein, and -:also :incloses the elbow outlet andall being openat the back end. The conical suction tube 13 is so positionedwvithin thecasing 11:asto provide openings ;both,ab,ove :and below the cone tube, allowing air to pass over and around the outlet opening 12, causing a vacuum and suction .on {the outlet opening when the automobile isin motion. The casing -11.

'may be made of a flattened tubular section V as illustrated in the drawings, or zitinay be 1 oftthefauto'body and surrounding the-outlet.

made a conical formation :having the larger conical-end in front-and the smaller conical end of thegca-sing positioned toward the rear opening -12 in the same manner :as illuscrease man velocity over the 'tubularzelbow 7 outlet 'l2., and slightly increase the air suction thereon. ,Within the :inner end :of

thetubularelbow '8- is mounted regulating valve 1f4 'vpivotally mounted I therein by the shaft 15' and "may be turnedto-any position for closing orwregulating-the passage and amount of ventilation within the auto body. Any :type of regulating valve which will control the-size of r s the tube passage will operate as well :and

may :be substituted therefor.

Zhemmy device is installed within .an automobile body, as illustrated in 'Figs. 11 to .15 1nclusive, theroof air currents are intercepted by-the deflector shield 2 and injected through the tube opening 3,. directly into the ventilator tube -1-. When .the .car is in motionair is forced through the suction casings 7 attached to' the outside body walls, causinga vacuum or suction on the outlets--12- and creates arlraftjthrough the ventilator'and will ma terially lessen and deaden the noise or roar commonly experienced in a closed auto body.

It is "apparent that my vdevice is subject to various modifications without departing '"fr'o'mthe spirit of my invention, as is illustrated by the alternate forms of construction. Figs. 6 and 7 illustrate an alternate form {of ventilating tube utilizing perforations 16 therein instead of the open section illustrated Sin Fig. 4, and substantially with the same results. .Also variousdesigns :of suction casings may besubstituted for the ones illustrated on the drawings for causing an air :suc'tion :on the :outlets '12-, and in cases where more inexpensive designs .are requiredthe casings 7-v nlay be omitted :alt-ogether, resulting in substantially :a perforated ventilator ipipe installed within the auto body :and having the ends projected through the side body walls and turned back toward the rear :of the :auto body. Also, if desired the deflector shield 2- may he omitted as illustrated in Fig. 115 although the resultin'g device will be less effective in ii-ntercept1ng the circulating rooffair currents. Figs. 12and'14 show the device as mounted with an :automobile body as an :accessory, while Figs; I8 and show the same device built in as a partzofthe body structure. The operation is the same in all cases. I
